AT32UC3A3256-ALUR – ATMEL

The AT32UC3A3256-ALUR is a high-performance 32-bit microcontroller based on the AVR32 UC RISC processor architecture. Fabricated in a low-power process, it features a 256KB embedded flash memory for program storage and 64KB of SRAM for data manipulation. The device operates at a maximum frequency of 66MHz, enabling execution of up to 82 DMIPS. Peripheral integration includes a 10-bit ADC with up to 16 channels, multiple USARTs, SPI interfaces, I2C modules, and a USB 2.0 Full-Speed device interface. Advanced features comprise a multi-channel DMA controller, a programmable interrupt controller, and a real-time timer. The AT32UC3A3256-ALUR is housed in a 144-pin Low-profile Quad Flat Package (LQFP) with a 0.5mm pin pitch, facilitating surface-mount assembly. The operating voltage range is typically 3.0V to 3.6V.
